Annis,
I love all of your tips! I am now trimming all of SOTTT HSTs, because I did not do that before I cut the batik HSTs down by 1/4, and they are not lining up very well, due to the different sizes! And, I don't know why I didn't think of taking the HSTs apart if there are two lights together and two mediums together, and just swap them to have two new HSTs with a light and medium. Makes so-o-o much sense! I'm not knocking those people who didn't have a high contrast, because I am sometimes guilty of focusing on color, and not paying enough attention to value. Looking forward to seeing your completed "Split Rail!"
Dawn,
